摘　　要：目的 :评价磁共振胆胰管造影在胆系结石中的诊断价值。方法 :采用MRCP检查和诊断为胆系结石的 1 2 0例病人与手术和临床诊断及其它影像学检查作比较分析。结果 :MRCP诊断胆系结石总准确率为 79.6 % ,MRCP结合原始MR图像诊断胆系结石总准确率为 92 .3%。MRCP结合原始MR图像与MRCP、US的总准确率比较 ,McNemarχ2 检验 ,P <0 .0 1。MRCP结合原始MR图像与CT、ERCP/PTC的检出率比较 ,Chi2 检验 ,P >0 .0 5。结论 :MRCP结合原始MR图像对胆系结石的诊断有较高的检出率 ,了解和熟悉MRCP的诊断误区 ,可进一步提高胆系结石的诊断准确率。Objective:To evaluate MR cholangiopancreatography (MRCP) in diagnosis of biliary stones.Methods: 120 patients with biliary stones diagnosed by MRCP were compared with surgical findings and clinical diagnosis as well as other imaging examinations. Results: The diagnostic accuracy rate of MRCP was 79.6%,and the diagnostic accuracy rate of MRCP combined with the source MRI was 92.3%.The difference between the latter and the total accuracy rate of MRCP and US was significant by McNemar χ 2 test ( P <0.01).The detection rate of MRCP combined with the source MRI was not significantly different from that of ERCP/PTC by Chi square test ( P >0.05). Conclusion: MRCP combined with the source MRI has high detective rate for diagnosing biliary stones. To get knowledge of misdiagnosis or blind area of MRCP can improve the diagnostic accuracy of biliary stone. PTC may be replaced by MRCP in diagnosis of biliary stones.
